Mein Auto: 08 X3, 08 Harley FLSTC

I ran a 2000 Jetta for 140,000 miles and tried different grade fuels with no perceptable change - a dealer mechanic said it was a great idea because he would get paid to clean my injectors - never happened. My Harley calls for 93 - it burns 87 fine. The BMW doesn't seem to know the difference - we put 70K on it. If a modern vehicle with electronic systems can't adapt to different fuels (winter grade, summer grade, etc), fix it, jumk it or trade it.
